Thanks! Will alter feeding schedule then. See if that improves things. Came home today and did a test of water. It's been less than 24 hrs and already ammonia and nitrite levels are in stress zone. Doing another 50% water change, but is that normal to have levels that high again in only 1 day?
Also, my heater has a white fuzz on it. It's always getting this fuzz in between water changes, which is partly why I've always done 100% changes, washing the heater and rocks each time. Think that's the fungus in the water? Will adding tri sulpha to water to treat bilbo clear this up, also? Or is there something else, some other kind of additive, I should permanently add to the water to treat this?
